Laboratory experiments and modelling of the geochemical interaction of a gabbro...
Berrezueta, Edgar; Moita, Patricia; Pedro, Jorge; Abdoulghafour, Halidi; Mirão, José; Beltrame, Massimo; Barrulas, Pedro; Araújo, AlexandreThe potential for mineral carbonation of carbon dioxide (CO2) in a plutonic mafic rock is addressed in this work through a set of laboratory experiments on a gabbro-anorthosite sample from the Torrão - Odivelas Massif (Portugal). The experiment was conducted in two stages under pressure (8 MPa) and temperature (313.15 K) conditions similar to those expected around a CO2 injection well. Stage-I simulated dissolu...

Pedro, Jorge; Carneiro, Júlio; Moita, Patricia; Berrezueta, Edgar; Araújo, Alexandre; Marques, Fábio; Pinho, Catarina; Caeiro, HelenaThe InCarbon project assessed the potential of gabbroic rocks for CO2 storage in alentejo. Lab carbonation experiments were carried out on gabbroic rocks from the Sines and Odivelas massifs. After gabbroic samples exposure to supercritical CO2-rich brine inside an autoclave, for 90 days, the XRD analysis reveals the presence of dolomite on sample surface, whereas the chemical mapping, by SEMEDS, suggest a spati...

Moita, Patricia; Berrezueta, Edgar; Abdoulghafour, Halidi; Beltrame, Massimo; Mirão, José; Ribeiro, Carlos; Barrulas, Pedro; Pedro, JorgeThe focus of this research is a qualitative study of mineralogical and chemical changes in plutonic mafic rock samples after exposure to a CO2-rich brine, under supercritical conditions (SC), to clarify the behavior of brine and rock in the initial stages of mineral carbonation. The studied rock consists of a gabbro-anorthosite from the Odivelas massif, in southern Portugal. The sample was exposed to a SC CO2-r...
Basic plutonic rocks: an unconventional solution for CO2 storage through minera...
Carneiro, Júlio; Moita, Patrícia; Pedro, Jorge; Berrezueta, Edgar; Abdoulghafour, Halidi; Marques, Fábio; Araújo, Alexandre; Beltrame, MassimoCO2 capture and geological storage (CCS) is recognized as an essential technolo-gy to achieve carbon neutrality and the Paris Agreement targets. The success of in-situ mineral carbonation of CO2 in basalts accomplished in the Carbfix project, opened up the prospect for considering other igneous rocks as viable targets for CO2 storage. The InCarbon project embraced the challenge to test the potential for mineral...
Experiments on mineral carbonation of CO2 in gabbro from the Sines massif – fir...
Moita, Patrícia; Berrezueta, Edgar; Pedro, Jorge; Miguel, Catarina; Beltrame, Maximo; Galacho, Cristina; Mirão, José; Barrulas, Pedro; Araújo, AlexandreThe InCarbon project based on the principles of CO2 capture and storage technologies, aims to study the potential of in situ mineral carbonation in mafic rocks in Alentejo. The gabbro of Sines massif was selected for the first laboratory test of mineral carbonation due to its geochemical, mineralogical and textural characteristics and proximity to the main focus of CO2 emissions in the region. Gabbro specimens ...
Mineral Carbonation of CO2 in Mafic Plutonic Rocks, I—Screening Criteria and Ap...
Pedro, Jorge; Araújo, António; Moita, Patrícia; Beltrame, Massimo; Lopes, Luis; Chambel, António; Berrezueta, Edgar; Carneiro, JúlioThis article describes the screening, ranking and characterization of ultramafic and mafic rocks in southern Portugal for mineral carbonation as an alternative to conventional CO2 storage in sedimentary rocks. A set of criteria including mineralogy, structure, surface area, distance to CO2 sources, expected volume, and socioeconomic conditions was applied to screen ultramafic and mafic rock massifs in the Alent...
